UNITED STATES WILLIAM E. Davis, or emmsm, mcnmm.

mrxsxm na'vrcn T all may concern:

Be it known that I, WILLIAM E. DAVIS, a

citizen of the United States, residing at Genesee, in the State of Michigan, have invented new and useful Improvements in Antiskid Devices, of which the followingis a s ecification.

- quickly connected to a tire and more eflicient part that is in its operation.

- An object of the invention is the construction of an anti-skid device of two parts, the one of which is permanently connected 'to the wheel so that when occasion demands the other partmay be quickly connected.

A feature of the invention is the novel manner of connecting each end of the chain to a clip so that the chain will be positively held against accidental removal in the use of the device but may be readily disconnected by manually forcing certain elements in a certain direction.

With these and other objectsin view the invention will be better understood from the following detailed description taken in connection with the accompanying drawing wherein:

Fig. -1 is a side elevation of the device.

Fig.- 2 is a vertical sectional view through a tire rim and felly showing my invention applied thereto.

Figure 3 is a sectional view on the line 3-3 of Fig. 1.

Figure 4 is a sectional view on the .line 4-4 of Fig. 3.

Again referring to thedrawing illustrating one construction of my inventlon the numerals 1 and 2 designate aair of cli s of a shape to bind against the si e of the elly 2 and having flan es 3 engaging the flange of the rim 4. A boIt 5 is arranged to direct the clips into binding en agement with the flange and rim. The c 1ps and bolt form a ermanently connected to the wheel. The etachable part consists of a chain section 6 having its end links connected to hook members 7. Each hook member has one end formed into T 8 so as to detachably en age therecess 9 in the clip and be forced t rough the slot 10 so as to detach the Specification of Letters Patent.

hook members from the clips. A coil spring 11 acting upon the washers 12 yieldably forces the hook member'into position to prevent accidental disengagement between the hook members and the clips.

From the foregoing description it will be seen that when my anti-skid device is being used it is only necessary to take the chain section and force same around the tire and the hooks through the slots. 10 into their proper connection with the recess .9. If a tighter connection is to be accomplished between the chain section and the tire the latter may be relieved of air pressure so that the connect ion may be made, when air is gam forced into the tire the pressure therea 0 will direct the various parts into engagement. For ordinary use it will not be necessary to remove the air as the chain section w1l automatically move into position to bring about proper engagement to prevent skidding of t e tire.

It is, of course to be understood that the invention may be constructed in various other manners and the parts associated in different relations and therefore, I do not desire to be limited in any manner exceptas set forth .in the claims hereunto appended.

Having thus described my invention what I claim is: c

1. An anti-skid device for automobiles comprising a pair of clips each shaped to engage the rim and felly of a wheel, a bolt for binding the clips into engagement with the felly and rim, a chain section, and a device for detachably' connecting each end of the chain to a clip consistin of a hook having a T shape end detachab y engagin the clip, and a spring arranged to force the hook into a direction to prevent accidental disengagement between the hook and cli 2. An anti-skid device for automo ile tires comprising a tread member assing around the tire, clips for detachab ie engagement with the wheel felly of the tire, anddevices connectin said tread member to the clip and capable 0 moving to two positions at right angles to each other for attaching or detaching the devices from the clip, and a spring arranged to normally hold the devices in attaching ition.

In testimony whereof I aflix my si WILLIAM E. D
